I kept having this wierd loud noise coming from my windshield. I think, I finally figured out what it was but why?? where the roll bar mounts up to the front windshield on the passenger side, the bolt on mount is cracking. this piece comes off the round tube and is sorta flat and two bolts hold it to the windshield. the flat piece has a crack radiating from the round tube outward almost to the end of the square flat piece. What would cause this??? Just old age and metal fatigue over time? i just put in a detroit locker, could this extra torque roll be causing the body/frame to flex more and this just turned out to be a weak spot??
